To all whom it may concern:

Be it known that I, SYLvEsTER L. Mc- ADAMS, a citizen of the United States of America, residing at Beaver Falls, in the county of Beaver and State of Pennsylvania, have invented certain new and useful Improvements in Water-Meters, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to water meters and has for its object to provide a device of such class which shall be simple in construction, strong, durable, eflicient in its use, inexpensive to manufacture and wherein friction is reduced to a minimum during the registering operation.

Describing the invention in detail reference is had to the accompanying drawings wherein like reference characters denote corresponding parts throughout the several views and in which Figure 1 is a plan of a water meter in accordance with this invention with the cover plate removed. Fig. 2 is a like view with the turbine wheel removed. Fig. 3 is a cross sectional view of the meter. F1g. 4 is a top plan. Fig. 5 is an inverted plan of the cover plate. Fig. 6 is a plan view of the turbine wheel. Fig. 7 is a cross section on line VIIVII of Fig. 6. Fig. 8 is a like view taken on line VIIIVIII of Fig. 6. Fig. 9 is a perspective view of one of the blades of the turbine wheel.

Referring to the drawing in detail, 1 de notes a cup-shaped member provided with a laterally extending annular flange 14, the member 1, said member and cover plate conis closed through the medium of the cover plate 6. The plate 6 is formed with a series of openings 11 which are adapted to register with the openings 12 formed in the flange 14 and through the said alining openings extend bolts 15 carrying nuts 16, said bolts and nuts securing the cover plate to the member 1, said member and cover plate constituting a casing for a turbine wheel to be hereinafter referred to. The member 1 is supported upon the legs 2, these latter being suitably connected with said member. The cover plate 6 is formed with a segmentshaped slot 7 which establishes communication between the chamber 1 and a segmentshaped enlargement 5 which is formed integral with or otherwise connected to the outer face of the plate 6. The segment-shaped hollow enlargement 5 terminates in a tangentially extending inlet pipe 3 which is adapted to communicate with a motive fluid supply. The member 1 is formed with a segment-shaped slot 10 which is arranged at substantially right angles with respect to the slot 7, the said slot 10 communicating with an outlet pipe 4 through the medium of a hollow enlargement 9 which depends from the lower face of the member 1.

The inner face of the cover plate 6 is formed with a circular depending portion 17 and between the said portion 17 and the bottom of the member 1 is positioned a double-rimmed turbine wheel 18, the rims of the wheel being connected together by radially disposed ribs 20 arranged at the top thereof. The hub of the wheel is indicated by the reference character 22 and is connected to the inner rim by the spokes 19. The hub 22 is fixedly connected to a shaft 21 having each end thereof formed with a seat 23 in which is mounted a bearing ball 24, the said balls being retained in position throu h the medium of adjustable screw threaded plugs 25, one of which extends through the cover plate 6 and the other of which through the bottom of the member 1.

Mounted adjacent to each one of the ribs 20 is a blade 26 which is pivotally connected to a pin 27, thelatter being secured to the rims of the wheel 18. The latter is suspended within chamber l and the length of the blades 26 is greater than the depth of the chamber 1 so that during the revolving of the turbine wheel the blades 26 will travel on the bottom of the chamber. Secured to the bottom of the chamber 1 is an arched shaped elevating'member 28 having angularly disposed ends 29 which are inclined with respect to the body portion of the memher and upon said member the plates 26 are adapted to travel, the inclined ends 29 facilitating the riding on and off of the blades 26. The elevating member 28 is positioned upon the bottom of the chamber .opposite outlet port 10' as clearly shown in Fig. 2.

Projecting laterally from the hub 22 is a pin 19 which is adapted to engage the teeth of a star wheel 20 which is interposed between the wheel 18 and the lower face of the cover 6. The star wheel 20 is supported by a shaft 21 which extends upwardly through the cover 6 and into a stufling box 22 mounted on the outer face of the cover 6. The shaft 21 is adapted to operate a recording mechanism of a conventional form and which may be secured upon the cover 6.

The operation of the device is as follows: h Iotive fluid being supplied to the chamber l through the slot 7 it impacts against the blades 26, these latter hanging in the position shown in Fig. 3 of the drawings. As the blades 26 are longer than the depth of the chamber l it is impossible for these blades to be swung forward and as the water impacts with these blades it causes the revolving of the turbine wheel 18. During the rotation of the wheel 18 the water which is behind the blades 26 as these latter pass over the slot 10 will be discharged through the said slot and out through the port 1. As the wheel rotates the blades will be elevated by the member 28 and close the water zones between the rims of the wheel. When the blades move off the member 28 they assume an inclined position and are then impacted upon by the incoming fluid. During the rotation of the turbine wheel 18 the pin 19 engages the teeth of the star wheel 20 actuating the latter and thereby operating the recording mechanism so as to register the volume of water which passes'through the meter.

While I have herein illustrated the preferred manner of constructing the meter, yet it is to be understood that changes, variations and modifications can be inserted which come within the scope of the claims hereto appended.
